Molybdenum Disulfide

Molybdenum Disulfide Coatings

Molybdenum Disulfide Coatings (MoS2 coatings), also known as Moly coatings, are a dry film lubricant and are commonly used in applications where load carrying capacity, operating temperature, and coefficient of friction are primary concerns.  Moly coating is a combination of molybdenum disulfide lubricant and high performance resins.  The coatings are thermally cured and bonded to the base metal of the coated part.

Moly coatings provide effective lubrication in a wide range of loads, in many cases exceeding 250,000 psi, by transferring lubricant between the two mating surfaces, which helps to reduce wear and coefficient of friction.

Uses for molybdenum disulfide coatings include applications that require a lubricant that is more nonreactive when in use, and remains sturdy.

We offer Molykote coatings, Everlube coatings, Lube-Lok coatings, Perma-Slik coatings, Ecoalube coatings, Ever-Slik coatings, and more.
